I strongly dislike the fact that this does not have a standard object class assigned to it (at the very least it should be labeled "Euclid" instead of "Pending"), and I see absolutely no in-universe reason for there to be a poem on the top of the document, in exactly the place where there wouldn't be one in a formal scientific document.

When an SCP-2601-1 instance expires, either due to instability or physical trauma, it will emit 53±6 rads of ionizing radiation, then explode with an energy of up to 45x 10^6 J.

A rad is an unit of absorbed dose, not an unit of emission. It makes no sense. I'm pondering.. watts per square centimetre might be better units, along with the time during which they emit.
I'm also wondering at how was this brief radiation toss-out even noticed when the main effect is detonating with the energy of 9kg of dynamite. I'm tempted to assume everyone close enough to get radiation sickness would be dead due to that, but then, there might be residue in the enviroment - I dunno because the unit used doesn't describe what they radiate. Also, what type? Alpha particles? Beta particles? Gamma rays?

Secondly, I'm finding it odd that he's feeling suddenly better in 1948, when there was the whole of WWII beforehand (He sure might have forgotten about it, but like, the researchers are also seeming to assume this), the maybe a decade of pre-war posturing not all that different from the beginnings of cold war.

EDIT: Moving the text elsewhere (maybe) with a header saying something along the lines of "today's text for protocol BRAVADO" might work better from an IC perspective.

Seconding VAElynx on the radiation part. Besides, rads are kind of outdated. The current dose unit most widely adopted by nuclear professionals is sieverts, most commonly in microsieverts per hour. That also happens to be what my Geiger counter measures in, and it's a pretty standard model.

All right, I'll definitely redo the radiation section. Yes, it is gamma rays. I'm, uh… well, let's just say I'm an historian and not a physicist. So what units should I be using, and if it is watts/area/time, how many watts?

Let's go with some manner of joules, because we don't know the time scope of the release and we can say it's pretty close to an instantaneous burst - hence the integral matters.

You said originally 56 rads, roughly. Let's try to translate in what you perhaps meant - that a human within some distance of this burst receives 56 rads of radiation.

now, to make this true.
1 rad = 0.01J/kg. Let's say for simplicity an average human is 80kg heavy. Gives 0.8J as a dose deposited.
Now… in what conditions is it deposited. An average (for our purposes) person might measure 1.7 metre, and be what, 50 cm wide, roughly (usually, it's how trousers are numbered - half the circumference. Well, Mine are like 58 but that's because the lynx is a fatass)
Which gives an area of what, 0.85m2.
Now is where it gets tricky.
Let's assume, for these distances, that the body of the effigy is a cylinder-shaped source, because it strikes me as a far better assumption than a spherical one.
Therefore, we can discount the height axis, and only worry about the 2D case.
Now, let's say that the distance to receive this dose is ten metres.. it's an order of magnitude estimate because, TBH , blast radius of dynamite is a little hard to find offhand XD.

Now we have a 1.7x0.5 cylinder arc section from a (let's assume 1.7)x2*3.14*10 cylinder shell. As you can probably see, the ratio of the two increases linearly with radius.

So we get. 0.8/(1.7x0.5)= 0.94 J/m2 at 10m from the source, and more sensibly, 9.4J/m, which is saying the same. Even better, we can take the entire area of an unit cylinder and make this something between 100-150J worth of gamma rays radiated out uniformly.

tl;dr, Maybe, given the nature of the event, saying that the object instantaneously radiates appr. 150J in the form of gamma rays spreading uniformly from the explosion centre wouldn't be too bad.

"Pending" is perfectly fine, in my estimation, but I'm not sold on the format screw otherwise. I mean, it's said there needs to be an excerpt at the top, but not why. For something so out of the ordinary, I think an explanation of some sort is in order.

However, that's easily ignored. The rest is great. I like that you essentially made something out of junk that nevertheless feels pain and age. I love the historical content. I definitely like the "another Foundation person got too close to a skip" angle at the end, and I'm enjoying this lingering sense of, did it actually want to be contained, or did it just need us to feed it until it was fit to return to duty, as it were?

Nah it's cool. I liked the format screw but it doesn't give that much of a good reason to be there. As for the "Pending" debate, I really don't care. The rest of the article was interesting enough and I thoroughly enjoyed reading it. Upvoted.

I find this to be more style over substance. The presentation is definitely cool and drew me in, but it had a really weak payoff.

There needs to be a better in-universe reason for the poems to be there. As it is right now, there isn't much of one at all. It's just, "Put it there because we said so, it looks pretty". Also, other points brought up, like this thing supposedly being omnipotent, also are rather hand-waved. This stretches suspension of disbelief way too far. But instead of us being given some information, the story just abruptly ends with the weapon thing dying before I can form any attachment to it.

I will say that the complaint about the object class that others have made is more of a nitpick in my opinion, but all the other problems ruin this one for me. This just feels sloppily put together.

They mentioned it was omniscient (all-knowing), not omnipotent (all-powerful). The omniscience is elaborated on later in the article where it talks about military stuff it should have no way of knowing.
